This invention relatesto separable fasteners of the class in which one ofthe separable part-s comprises a stud, and the other means which clasps about and interengages With the stud to'retain the two parts in their assembled relationship. Y

The invention aims to provide a compact Vfastener suitab-le forfa-stening buttons and emblems to garments, and for other uses, and

3 10 toprovide a fastener which shall be positive lin its action, so thati there shall be no acci- ?dental separation ofthe parts.

The invention Will be bestlunderstood by reference to the following description, when T taken in connection 'with' the accompanyino' jdravvings ofone specific embodiment thereof, While its scope Will be more particularly pointed out in the appended claims.` l

In the drawings:

exemplifying the inventitni;`

' Fig. 2 is'avsectional vview on line2-2 of Fig. 1;

. f Fig.3 is a'sectional View on lineS-E 'of i "2'5 Fig. 2, showing the parts in their 1normal po'- sition-that'is to say, locked and Y Fig. 4 is a similar sectional view, showing the parts as theyl appearlrvhen unlocked. Referring to the drawings, and to the emtrated therein, there is shown a separable fastener comprising a stud 5, Whichv may be attached to an appropriate base 6, such as a button. The stud is provided With a head "i, and is grooved to present a neckl 8. The head has a rounded pointV toV enable it to enter the other part easily. The other part comprises a shallow, cup-like casing 9, havinga Wall '10 provided vvith a central opening 11, which receives the stud. The casing is provided with acover, hereinl a disk or plate 12, conveniently secured 'tofthebody of the casing, as by providing ythe'latter .With an annular 'groove'l for the margin of the cover,l the latterV being secured in place by providing the body1 With an inwardly-directed flanges'14'. overly-ingthe outer face of the margin of the'cov'erl lAfter the :parts are assembled. this: flange isr pressed or spunjdovvn into the position 'shovvnfin Fig-2. Y

Fig. 1 is an elevation ofa separable fastener vbodiment of the invention which is illus-v Referring nowl to Fig. 3', the stud is normally locked bynieans interlocking there,- With, comprising a plurality of spring arms 15'-, herein conveniently formed as integral parts of a disk or plate 16, conveniently held against rotation in the casing, as by providing the plate With one or more notches 17to, receive projections .18 formed 4by f squeezing the circumferential v'vall ofi the casing into the notches. 'i V Thearms are actuated 1neans,"her`ein,a disk 4or plate 19 (see Fig; 2v),

'by actuating interposed betWeen'the plates12 and A16,and y presenting a plurality'ofv actuators, herein bosses 20Which are normally4 engaged with the respective arms 15 to hold lthelatter positively in interlocking engagementwithk the studf `This is conveniently accomplished by providing each ofthe arms-With aconcave seat 21j tof receive one of thebosses.y Before the boss reaches thed'epression it hastok ridev lovera slight hump 21 and thus spring the4 l arm very slightlyfbefore the boss canl enter the depression.' Converselythe boss has to ride over this hump and thus sprino' the arml beforethe latter can beunlocked. f he arms also present cam-paths 22, f `appropriately formed for cooper'ationwith theb'osses 20,'so that When the actuating kplate is rotated clockwise, as vievved in Figs. 1 and 3, from `the position shoivnin Fig. 3 tothe position shown in Fig. 4:, thebosses Will ride up inclines presented by the cam-paths, 'and Will force` the arms out of engagementvvith the stud. The arms Will then be locked in this position ,until the actuating plate Ais rotated in the opposite direction. f When the arms are thus v retracted, the stud may be Withdrawn from the casing.` f

Thus it is evident that the fastener is positively locked and unlocked byfthe rotation of the actuating plate,.and that vvhen the stud is:locked inplace,`accidental separation of the parts is-impossible. Rotation of the actuating plate is conveniently accomplished by providing on its outer` face anjappropria-telyshaped linger-piece 28, conveniently secured vto the plate, as by providing the latterrvitlji an integral, vholloWboss 2 4, shouldered as at 25 to receive the finger-piece, andV flanged over shown in Fie'. 1. 1o e Y Y Hevme' thus Clescnbeclone .emlioeiment ci..

as at 26 to secure the finger-piece lixedly to `the plate. This hollow boss, by the way, provides a space to receive the head 7, and this construction contributes in constituting an eX- tremely shallow, compact fastener.
